If you work in GitHub Desktop, you will be able to simultaneously change many files, and save them without making a commit.
On GitHub Desktop, when you’re ready with all your changes, you make a single "commit" for all those changes together.
This method is the best one for making a series of changes, or if you will be a frequent contributor, because it lets you save a local copy of your work and make as many iterations to as many files as you like before sending a coherent and complete package to be merged into the main repository.
This method works best in conjunction with an editor called VS Code (which stands for "Visual Studio" Code, which is a Microsoft project.)
VS Code is the most widely used editing program for software in the world.
It has modular plugins for every computing language in the world as well.
For ProjectLiberty2029, I, Vector Hasting, am using the "Asciidoc by asciidoctor" extension.
It allows VS Code to edit-check the asciidoc syntax as I write it.
It also gives me the option of previewing the webpage inside VS Code, though I generally use a jekyll environment to do that.
We will have more complete instructions on these tools later in this document, though as of this draft of this document, those tools are not explained.
